ABSTRACT:
A golf ball comprising a core; an intermediate layer having a flexural modulus of between about 65,000 psi and about 120,000 psi and being formed from a polymer blend comprising a first material selected from the group consisting of thermoset polyurethanes, thermoset polyetheresters, and thermoset polyetheramides and a second material comprising a grafted-metallocene polymer; and a cover layer comprising a castable reactive liquid thermoset polyurea.
